44 ACT2000 USER GUIDE
3.8 Changing Set-Up Parameters
The ACT2000 uses a number of variables to define its functionality.
These variables are called Set-Up parameters and they are stored in the
EEPROM in the ACT2000. Default values for these variables are loaded
into the EEPROM at the PECC factory. The Set-Up parameters are
reloaded into the system registers each time the ACT2000 is powered up
or reset. See Table 3-5 for typical Set-Up parameters.
Users can change the Set-Up parameters to better suit their specific
applications. These parameters are uploaded to the ACT2000 via the
RS232 interface using PECC’s ActWiz software. The Set-Up parameters
can only be accessed when the ACT2000 is in the Power Up / Set Up
state. See the Basic Operation Flow Chart in Figure 3-2 and the Power
Up / Set Up State section below for details.
Contact PECC for a copy of ActWiz software. See the ActWiz Software
Manual for further details.
Power Up / Set-Up State
The ACT2000 is in Power Up / Set Up state immediately after the
ACT2000 has been powered up or reset. This is after the system
registers have been cleared and the Set Up parameters have been
reloaded, but before the Homing process has begun (RUN command =
OFF). This is the only state in which the user can communicate with
ACT2000 via the RS232 interface. In this state, a set-up file can be
downloaded to view the current Set-Up parameters or uploaded to
establish new Set-Up parameters. A Fault file can also be downloaded,
also using the ActWiz software. Please see the ActWiz software manual
for more information.
WARNING
Property Damage Hazard – The ACT2000 will not hold position when
communicating with ActWiz software. Ensure there is no load on the
extension rod when communicating with the actuator.
A fault file also can be downloaded when the ACT2000 is in the Power Up
/ Set Up state by using ActWiz software via the RS232 interface. The fault
file will provide fault information and possible causes
